I'm often asked about batteries and their capabilities. The following data
comes from RAY-O-VAC corporation and compares their Renewal rechargable
alkaline batteries to several other popular portable technologies. One point
that is not clear here is that at the end of the 25 charge cycles for the
Renewal batteries, the battery is not dead, is still has the same amount of
energy available as a new NiCad, which are high current devices, but are low on
total energy available.
